Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 50428 MMBtu 52162 MMBtu
Electricity from on-site renewables 50.04 MMBtu 0 MMBtu
District steam/hot water (sourced from offsite) 0 MMBtu 0 MMBtu
Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) 89622 MMBtu 110118 MMBtu
Total 140100.04 MMBtu 162280 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year July 1, 2017 June 30, 2018
Baseline Year July 1, 2004 June 30, 2005

A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):
---

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 1630898 Gross Square Feet 1145166 Gross Square Feet

Source-site ratio for grid-purchased electricity:
3.14

Total building energy consumption per unit of floor area:
Performance Year Baseline Year
Site energy 0.09 MMBtu / GSF 0.14 MMBtu / GSF
Source energy 0.15 MMBtu / GSF 0.24 MMBtu / GSF

Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
36.42

Degree days, performance year (base 65 °F / 18 °C):
Degree days (see help icon above)
Heating degree days 5232 Degree-Days (°F)
Cooling degree days 173 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 215521 Square Feet
Healthcare space 0 Square Feet
Other energy intensive space

EUI-adjusted floor area, performance year:
2061940 Gross Square Feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
12.57 Btu / GSF / Degree-Day (°F)

Documentation (e.g. spreadsheet or utility records) to support the performance year energy consumption figures reported above:
A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):
---

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):

Evergreen uses a district steam system for campus heating. Steam pressure has been reduced and building warm-up times have been moved closer to the start of each day and customized, in conjunction with space scheduling, to end prior to the end of occupancy time in each building.


A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

About 95% of the parking lot and external lighting is LED, including street lights and walkway lighting locations.

All internal lighting was changed to CFL's in 2006 - 08, and we're now transitioning to LED's as bulbs and/or fixtures fail. Roughly 1% of total indoor space uses LED lighting, including some residential applications.


A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

A student-originated and designed passive solar, aquaponics greenhouse was constructed near the campus residences in 2013. Student workers on the Residential Facilities crew have also built and maintain a compost heating system (radiant floor) for one of our duplex residences.


A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
---

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):
